Description

Corrugated paper box with additional layers at key positions

Technical Field

The utility model relates to a packing field, more specifically relate to a corrugated box.

Background

Corrugated boxes are widely used packaging products, and are particularly used in the fast consumer goods industry in a huge amount. Corrugated cartons on the market at present are all made of corrugated paperboards by one or more processes of printing, slotting, die cutting, box nailing, box adhering and the like through mechanical equipment, the box types of the corrugated cartons are various, but the material layer number of each part on the same corrugated paperboard is the same no matter which box type carton is on the market at present, and when the cartons are used, some physical properties of some parts are insufficient or some physical properties of some parts are excessive, so that the protection of packaged articles is insufficient or the materials used by the cartons are wasted. Particularly, the standard grooving type carton, international standard 0201 box type, is made of a single corrugated board, the whole carton is opened and flattened at an opening joint to form a corrugated board with grooves, after the carton is folded into the carton, the upper surface and the lower surface of the carton consist of four rocking covers and four bottom covers, and a plurality of parts are overlapped, so that the upper surface and the lower surface are wasted due to excessive use of materials, conversely, the four side surfaces are insufficient in physical performance due to the fact that the four side surfaces only consist of the single corrugated board while the upper surface and the lower surface just meet the performance requirements, and if the compression resistance and the breakage resistance data do not reach the standard, the protection force for packaged articles is insufficient.

Based on the above disadvantages, the present inventors propose an innovative corrugated carton to solve the existing disadvantages.

Disclosure of Invention

The utility model adopts the technical scheme as follows:

the corrugated carton that key position adds layer, its characterized in that: the additional layer is formed by adding the layer number at a position needing to be reinforced of a certain corrugated paper board of the corrugated paper box, so that the physical performance of a key position is enhanced, the added paper layers are bonded through glue and are integrated with the original whole paper board, and the use convenience of the new paper box is ensured.

While the additional corrugated structure may be constructed of a corrugated sheet and a face sheet, in order to achieve a higher performance, in another case, it is possible to add a corrugated sheet and a face sheet to the original additional corrugated structure.

The important parts are two conditions, one is to add layers on four side surfaces of the carton, and the other is to add layers on four side surfaces of the carton and the bottom surface of the carton simultaneously.

The overlay may be based on any corrugated board and any number of layers.

The beneficial effects of the utility model

Can increase the resistance to compression and the bursting strength of four sides of carton alone, can increase the bearing intensity of carton bottom simultaneously to product in the better protection carton. The paper material that whole carton used can be reduced when guaranteeing the resistance to compression and the bursting strength of four sides of carton to reduce packaging cost.

Detailed Description

Referring to fig. 1 and 3, a corrugated case with a layer added to an important portion is a corrugated case with a layer added to an important portion on four sides (2 in fig. 1), which are four supporting surfaces of the case, and a layer of corrugated paper and a layer of face paper (4 and 5 in fig. 2) are added to the original paper corresponding to the four sides, i.e., a single corrugated structure (1 in fig. 3) is laminated, and the laminated paper and the case are integrated, thereby ensuring the convenience of use of the case. The four sides of the carton with layers in the important parts have two layers of paper (4 and 5 in figure 4) more than the top and bottom of the carton, so that the compression strength and the bursting strength of the important parts are increased, and the data of the aspect is equivalent to that of a double-corrugated carton with five layers of paper in the whole, thereby playing a role in strengthening the protection of the package in practical application. Conversely, if the compression strength and the burst strength of the important parts of the carton originally need to be achieved by using a double-corrugated case with five layers of paper, the top surface and the bottom surface of the corrugated case with the layers added at the important parts need to have two layers of paper less than four side surfaces, so that the paper materials of the top surface and the bottom surface of the carton can be saved while the performance requirements of the compression strength, the burst strength and the like of the important parts are met. For example, in the case that a single box of packing material is not very heavy, but needs to be stacked and arranged on a tray in multiple layers, the box is most suitable in the case, because the case has higher requirements on the compression resistance and the burst strength of four sides of the box, but has lower requirements on the top surface and the bottom surface of the box, the stacking stress is on the four sides of the box, the burst resistance is basically on the four sides, the bottom surface of the box only bears the gravity of the packing material in the single box, the top surface of the box is not greatly stressed, and the materials of the top surface and the bottom surface of the box are overlapped after the box is closed, so the bottom surface and the top surface do not need to have the same number of layers as the four sides to meet the service performance.

According to the above embodiment, another embodiment is developed, as shown in fig. 5 and 6, a corrugated carton with a layer added in an important part is a corrugated carton with four side surfaces and a bottom surface (1 in fig. 5) as important parts, the four side surfaces are four supporting surfaces of the carton, the bottom surface refers to four bottom flaps, a single corrugated structure is covered on the original paperboard of the corresponding parts of the four side surfaces and the bottom surface, and the covered paperboard and the carton are integrated, so that the convenience in use of the carton is ensured. The four side surfaces and the bottom surface of the corrugated case with layers at the key positions are made of two layers of paper (4 and 5 in figure 6) more than the material of the top surface of the corrugated case, so that the compression strength and the burst strength of the key positions are increased, and the data of the aspect is equivalent to that of a double-corrugated case with five layers of paper as a whole, so that the corrugated case has the function of strengthening the protection of the package in practical application. Conversely, if the compression strength and the burst strength of the important parts of the carton originally need to be achieved by using a double-corrugated carton with five layers of paper, the paper material of the top surface of the corrugated carton with the layers added to the important parts needs to be less than two layers of paper on four side surfaces and the bottom surface, so that the material of the top surface can be saved while the performance requirements of compression resistance, burst resistance and the like are met. For example, in the case that a single-box container is relatively heavy, but needs to be stacked and arranged on a tray in multiple layers, the stacking device is most suitable in the case, because the requirement on the compression resistance and the burst strength of four supporting surfaces of the carton is higher, and the bottom surface of the carton needs to support the heavy container of the single box when the single box is carried, the requirement on the supporting force of the bottom surface of the carton is higher, but the requirement on the top surface of the carton is not high, the stacking force is basically exerted on the four supporting surfaces of the carton, the burst resistance requirement is basically exerted on the four supporting surfaces, and the stress on the top surface of the carton is not large.

In addition, according to the layer adding mode, the layer is added on the double corrugated board with five layers of paper.

The above description is only for the preferred embodiment of the present invention, and the technical solutions of the present invention are not limited thereto, and those skilled in the art can obtain the technical solutions after the changes for various reasonable transformations based on the disclosure of the specification, and the technical solutions after the changes are all within the protection scope of the present invention as long as they do not depart from the spirit of the present invention.
